Selection of horizontal container level gauges
Thread Content
Which is a better choice for a level gauge in horizontal containers? Process medium: liquid ammonia + gaseous ammonia (for measuring the liquid ammonia level). Medium temperature: -35 degrees. Medium pressure: +200 KPa; a fault in the process can result in a maximum negative pressure of -200 KPa. Which level gauge offers the best cost-performance ratio? (Radar and magnetically induced pricing are a bit high, so they’re not considered.)
A differential pressure transmitter (with isolation fluid) will suffice; pay attention to the selection – it’s unlikely that there will be a negative pressure of -200 KPA in the event of a process fault, right? ）
Differential pressure level transmitter; a magnetic float can also be used
